Narrated Anas:
Allah’s Apostle went towards the Khandaq (i.e. Trench) and saw the Emigrants and the Ansar dig –
ging in a very cold morning as they did not have slaves to do that for them. When he noticed their
fatigue and hunger he said, “O Allah! The real life is that of the Here-after, (so please) forgive the
Ansar and the Emigrants.” In its reply the Emigrants and the Ansar said, “We are those who have giv –
en a pledge of allegiance to Muhammad that we will carry on Jihad as long as we live.”
